LIVE, THIS IS PITTSBURGH'S ACTION NEWS 4. ALL RIGHT, WELL, AT LEAST IT'S NOT SNOW, RIGHT? MOWING THE GRASS CAN SEEM LIKE A FULL-TIME JOB OVER THE SUMMER, SO WHY NOT MAKE SOMEBODY ELSE DO IT FOR YOU? GREAT IDEA. TONIGHT, RAY PETELIN IS LETTING YOU IN ON A SECRET, AND YOUR NEIGHBORS WILL NEVER NOTICE A DIFFERENCE. Reporter: IT'S CONSIDERED SUMMER'S BIGGEST CHORE, MOWING THE LAWN, BUT WHAT IF I SAID YOU DON'T NEED A MOWER ANYMORE, ALL YOU NEED IS A SMARTPHONE? YOU KNOW, YOU MIGHT BE, YOU KNOW, SITTING OUTSIDE ENJOYING THE WEATHER WANTING TO DO SOMETHING AND YOU TAP A BUTTON AND BEFORE YOU KNOW IT, YOU CAN CHOOSE THE EXACT DATE OF WHEN YOU WANT SOMEONE OUT THERE. Reporter: YEP, THERE'S AN APP FOR THAT, WHETHER YOU JUST HATE MOWING THE LAWN, OR NEED A RESCUE FROM OUT OF CONTROL FESCUE, A NEW APP CALLED MOWS IS GETTING THE JOB DONE IN PITTSBURGH. HE USES THIS APP IN HIS NEIGHBORHOOD. WERE YOU SKEPTICAL? YES, AT FIRST. YOU KNOW, I'M NOT ELECTRONICALLY, YOU KNOW, TUNED IN ALL THE WAY, BUT, YEAH, I WAS. I'M VERY PLEASED WITH IT. Reporter: SO HOW DOES THIS APP WORK? IT'S SIMPLE. THERE'S ABOUT FOUR QUESTIONS, HOW HIGH YOUR GRASS IS, LOCATION, TAKE A PICTURE OF IT, SEND IT IN, THEN THEY DO THE QUOTE RIGHT OVER THE INTERNET. Reporter: SERVICE PROVIDERS USUALLY ARRIVE WITHIN TWO DAYS WITH AVERAGE COSTS BEING AROUND $35. BUT LONGER GRASS AND BIGGER YARDS WILL COST MORE PER CUT. ALL PAYMENTS ARE MADE THROUGH THE APP, AND THE FOUNDERS OF THE MOWS APP TELL US THEY VET MOWING COMPANIES FOR QUALITY AND GET PROOF OF A COMPLETED JOB EVEN WHEN YOU'RE NOT IN TOWN. EVERY JOB THAT'S COMPLETED, THERE'S ACTUALLY A PICTURE FOR VERIFICATION. IF YOU'RE IN FLORIDA, YOU KNOW, YOU KNOW YOUR JOB'S GOING TO BE DONE IN PITTSBURGH. Reporter: WHILE THE APP MAKES HIRING LAWN SERVICES EASY FOR THE CONSUMER, IT ALSO MAKES FINDING CLIENTS EASIER FOR THE LAWN SERVICE COMPANIES. I GET NOTIFIED TWO DAYS IN ADVANCE OF ANY JOBS AND I CAN SEND WORK ORDERS TO MY GUYS AND IT'S ON THE ROUTE. PRETTY EASY. Reporter: HOW MUCH OF YOUR BUSINESS WOULD YOU SAY IS FROM THIS APP? 40%. Reporter: 40%, THAT MUCH? YEAH, THEY DO A LOT OF BUSINESS. Reporter: THERE'S EVEN A WINTER VERSION FOR PLOWING,
